The objective of this study was to investigate the
differences of hippocampal volume and shape as well as the functional change between
long life experienced taxi drivers and controls of Korean population.
Three-dimensional T1-weighted images and blood oxygen level dependent
functional MRI(fMRI) were obtained from 8 subjects, consisting of 4
experienced (20 - 30 years) taxi drivers and 4 age-matched controls. The
hippocampal volume and shape were analyzed with three-dimensional T1-weighted
images. In addition, neuronal activities of brain were analyzed using a blood
oxygen level dependent fMRI between the two groups.
